SuperCPU (v2) was quickly released a higher capacity CPLD that enabled significantly more optimizations than the first version.

The SuperCPU was released in 1996 by Creative Micro Designs. It is perhaps the best known CPU accelerators for the Commodore 64 and Commodore 128. It was certainly the most compatible accelerator of its day. It distinguished itself in both speed and compatibility.

The first release of the SuperCPU (v1) was buggy and was not fully optimized. This was due to the fact that the first Altera CPLD used by CMD was too small to include all of the necessary optimization logic to ensure a high degree of compatibility.

The second release of the SuperCPU (v2) generally solved these problems. It included a higher capacity Altera CPLD which allowed for more highly optimized logic without exceeding the capabilities of the chip.

The SupeCPU was far from the first commercially successful CPU accelerator but it was the most certainly the most ambitious design.
